Certified

 

For many buying certified gemstones is a must especially when you never dealt with a vendor before.Remember a certification is not an appraisal. Appraisals give you a value for insurance purposes (many times 10-20X higher than market values), a certification is a laboratory fact based document based on the actual physical properties of the stone (or jewelry) A few do’s and don’ts with certifications.

Do-Make sure the certifying lab is reputable, make sure it’s a lab, not just a gemologist/jewelry store with some tools

Don’t-The person certifying a gemstone or jewelry should never be a person that sells gemstones or jewelry, it should always be an independent person with no vested interest in the sale

Some of the best gemological labs in the world in my humble opinion are 1.GIA Gemological Institute of America  https://www.gia.edu/

2. AGL American Gemological Laboratories http://aglgemlab.com/

3. AGS American Gem Society https://www.americangemsociety.org/

4. IGI International Gemological Institute http://www.igiworldwide.com/

5. GRS GemResearch Swisslab http://gemresearch.ch/

6. Gubelin Gübelin Gem Lab http://www.gubelin.com/

7. SSEF Swiss Gemmological Institute https://www.ssef.ch/

8. GIC Gemmological Institute of Colombo https://www.gicolombo.com/

10. GGTL Global Gem Testing Laboratory http://www.ggtlsl.com/
